Abstract: State Grid Corporatipon of China is promoting the construction of a new type of power system,which requires communication systems to have stronger coverage,more real-time transmission and greater capacity. Based on the analysis of technical system and comparison of remote access network in new power system,the remote access solutions are studied in power application scenarios.The results show that in the new power system,the optical fiber private networks are still the best option for the remote access network.5G communication technology has the characteristics of high speed,low delay,and large capacity,which is highly consistent with the mixed bearing requirements of massive new energy terminal access,control and collection services in the new power system.With the gradual maturity and improvement of the standards,the 5G technology and the private network constructed with 5G slicing technology will be widely used in the remote access network.
